Question about 1987 Ford Ranger

Fuel pump will not shut off

When I turn on the key the fuel pump will not shut off and my cylinders fill with gas. I took out the spark plugs and gas just shoots out the holes. I just replaced my fuel pump relay and the fuel pump is new. Any ideas?

    that has been suggested but I checked the fuel pressure with a guage (Truck not running, key on only) it is at 42 PSI and gas is still pouring out the spark plug holes. Maybe you know how the ECM relay or the Wide open Throttle relay relates to the fuel pump

    I have a F150 5.4L 1999 model. My truck won't crank but will turn over. The fuel pump stays on all the time. I can tap the relay and it goes off but won't crank. It's got great fuel pressure. Any subjection ?

Will not start


Gas, air, compression, and spark is all the cylinders need for the engine to run. No start is usually gas or spark related. Here's the fuel check on fuel injected cars. Turning the key to on will start the pump for 2 or 3 seconds to pressurize the system. When the engine is cranking over the computer turns on the fuel pump relay again, so the pump will be on. And stays on after engine is running to keep high pressure against the fuel injectors. The computer times the injector pulse to spray gas into the intake or into the cylinder at the right time.
So if you have a no start, to check for gas, listen for the pump- a distinctive hum or buzz from the tank, check the fuel pump fuse, see if you can feel or hear the fuel pump relay click when someone turns the key to on. (Did you remember to check if the tank has gas?). Finally, you would have to check for power on the fuel pump wire at the tank connector, while someone holds the key in start. If you have power there, it's likely you need a new fuel pump. If the pump is working, well and good, but keep in the back of your mind that a weak pump that puts out low pressure can cause hard starting problems and poor running. At any rate, if you have gas up to the fuel rail, the only other thing between there and the cylinders is the injectors. Are they working? A quick check would be to remove a spark plug or two after cranking the engine over a few seconds. If they are wet with gas, the injectors are injecting. Hope I've helped you out some. I know some people who say to spray some starting fluid into the air intake to check if you have a gas problem with starting- I've done it myself. But I've learned it's better to use carburetor cleaner spray instead, it burns cleaner and something about the potentially harmful effects of starting fluid, well. good luck.

1990 honda accord wont fire


Do you have spark, do you have fuel pressure? it is one of these or a camshaft timing problem. I would start with checking the spark at the plugs 1st.

I have a 1991 ford F150 6 cylinder with dual tanks. I just changed the oil,oil filter,fuel filter,air filter,and master brake cylinder last week and the truck was running good(started every day since)....


Hi :) That is normal. When you first turn on the key the prime relay kicks in for the gas pump then shuts off. Once you start the engine the fuel pump is restarted buildes pressure as the engine needs it. When you shut the key off the pump shuts down.You could check the fuel pump relay which is different then the prime relay or check the spark module on the distributor housing. And the wire that go to all control module have a bad habbit of cracking and turning green with corrosion.
